In her new spot, Simon now offers homemade ice cream that's churned on-site, along with "pice cream," an amalgam of pie and ice cream.

"Pice cream is part of my diabolical plan to make ice cream and dump a pie into it," she said. The flavors will change seasonally; this week, blueberry and tiramisu are available.

Although she softly opened last weekend, Simon will host an official grand opening event this Saturday, February 26th, with live music, an art show featuring the work of Kelly Nicolaison, and of course, pie.

Simon met San Franpsycho owner Christian Routzen at the SF Indie Mart in December. After sampling her pie, Routzen offered her an opportunity to set up shop at Sundays, the coffee and ice cream shop he added to his 9th Avenue location in 2015.

"This spot is perfect for us," said Simon. "There are lots of families, lots of people visiting the park. There's the N-Judah, so it's easily accessible, and there's other great food just within this block."

Simon told us that there is already talk of building out a parklet at the location, and putting in a full-fledged deck out back. She said she eventually plans to sell savory items as well.

"Elizabeth has a good existing community, one that reflects the 'maker' element of San Francisco," said Routzen. "People want to meet makers. They want to meet the faces behind things, and with what she has going on, people can walk in and talk to the actual person making the pies."

Demand for Revenge Pies has grown so much that Simon now works out of La Victoria Bakery in The Mission to produce "thousands" of pies per month. She also sells to local grocery stores (like Green Earth on Divisadero) and will appear at Off The Grid in Fort Mason, which kicks off on the first Friday in March.

Although her space at Sanfranpsycho is permanent, Simon said she's still seeking additional funding to grow even more. To that end, she's set up a GoFundMe page, where she's offering various rewards to contributors.
